Normalized solutions for fractional nonlinear scalar field equations via Lagrangian formulation
No full textWe study existence of solutions for the fractional problem (Pm)
(−Δ)su + μu = g(u) in RN,
RN
u2dx = m,
u ∈ Hs
r (RN),
where N 2, s ∈ (0, 1), m > 0, μ is an unknown Lagrange multiplier and
g ∈ C(R,R) satisfies Berestycki–Lions type conditions. Using a Lagrangian
formulation of the problem (Pm), we prove the existence of a weak solution
with prescribed mass when g has L2 subcritical growth. The approach relies on
the construction of a minimax structure, by means of a Pohozaev’s mountain in
a product space and some deformation arguments under a new version of the
Palais–Smale condition introduced in Hirata and Tanaka (2019 Adv. Nonlinear
Stud. 19 263–90); Ikoma and Tanaka (2019 Adv. Differ. Equ. 24 609–46). A
multiplicity result of infinitely many normalized solutions is also obtained if g
is odd

The long-wavelength view of GG Tau A: rocks in the ring world
No full textWe present the first detection of GG Tau A at centimetre wavelengths, made with the Arcminute Microkelvin Imager Large Array at a frequency of 16 GHz (λ = 1.8 cm). The source is detected at >6 σrms with an integrated flux density of S16GHz = 249 ± 45 µJy. We use these new centimetre-wave data, in conjunction with additional measurements compiled from the literature, to investigate the long-wavelength tail of the dust emission from this unusual protoplanetary system. We use an MCMC-based method to determine maximum likelihood parameters for a simple parametric spectral model and consider the opacity and mass of the dust contributing to the microwave emission. We derive a dust mass of Md ~ 0.1 Msun, constrain the dimensions of the emitting region and find that the opacity index at λ > 7 mm is less than unity, implying a contribution to the dust population from grains exceeding ~4 cm in size. We suggest that this indicates coagulation within the GG Tau A system has proceeded to the point where dust grains have grown to the size of small rocks with dimensions of a few centimetres. Considering the relatively young age of the GG Tau association in combination with the low derived disc mass, we suggest that this system may provide a useful test case for rapid core accretion planet formation models

Levi-Tanaka algebras and homogeneous CR manifolds
No full textIn this paper we take up the problem of discussing CR manifolds of arbitrary CR codimension. We closely follow the general method of N. Tanaka, while concentrating our attention to the case of manifolds endowed with partial complex structures. This study required a deeper understanding of the structure of the Levi-Tanaka algebras, which are the canonical prolongation of pseudocomplex fundamental graded Lie algebras. These algebras enjoy special properties, the understanding of which provided also a way to build up several different examples and points to a rich field of investigations. Here we restrained further our consideration to the homogeneous models
Classification of semisimple Levi-Tanaka algebras
No full textAfter showing that the partial complex structure is defined by an inner derivation, we give a complete classification of semisimple Levi-Tanaka algebra
